I had another look at this, and in fact filed a proper bug about it so I have somewhere to attach the build.log and root.log files: https://bugzilla.redhat.com/show_bug.cgi?id=2542352 However I'm still unable to reproduce this on anything except our Koji build servers. Since I can't understand why it doesn't reproduce locally, it's hard for me to fix anything. > First question - do we know if the NTFS driver in the kernel is any > good? The old one was _not_ which is why we stuck with ntfs-3g. This is still an important question. ntfs-3g is well-tested and battle-hardened and supports features we need like fstrim. We've used it to write drivers into literal millions of Windows virtual machines when doing conversions off VMware, and there has never been any suspicion of filesystem problems. Any kernel (or any alternate) NTFS implementation has a very high threshold to cross. I looked at the upstream kernel and I see there are now _2_ apparently active NTFS drivers, called "ntfs" and "ntfs3". Fedora builds both. The kernel documentation doesn't appear to cover anything about the history of these drivers or which one is preferred or what features they offer. It's a very confusing situation.
